Description

Technical Field

[0001] This utility model relates to the field of manual exploration and excavation assistance technology, specifically to a lever-type manual exploration and excavation lifting device. Background Technology

[0002] Before drilling for geological exploration, in order to reduce damage to underground pipelines, manual excavation to a depth of five meters is usually carried out. The excavation method is to use a Luoyang shovel to embed it into the soil, and after the hole is formed, the core sample is manually pulled out.

[0003] As the drilling depth increases and the Luoyang shovel becomes longer, the difficulty of manually pulling the Luoyang shovel out of the soil gradually increases. At this point, tools such as pipe wrenches are usually used to loosen the Luoyang shovel before pulling it out, which consumes a lot of manpower, has low work efficiency, and high construction costs.

[0004] Therefore, we propose a lever-type manual excavation and lifting device. Utility Model Content

[0005] The main purpose of this utility model is to provide a lever-type manual excavation and shovel lifting device. This device uses the lever principle and the limiting frame on the support frame assembly as the fulcrum. By pressing the lever, the limiting assembly can be driven to apply an upward lifting force to the Luoyang shovel handle. There is no need for manual labor to pull it out or loosen it with pipe wrenches, which greatly reduces the labor consumption and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A lever-type manual excavation and shovel lifting device includes a lever, a mounting rod, a movable sleeve, a limiting component, and a support frame assembly. One end of the lever is vertically connected to the mounting rod, and the lever is rotatably connected to one end of the limiting component via the mounting rod. The limiting component is sleeved on the handle of the Luoyang shovel, and the bottom end of the Luoyang shovel handle is fixedly connected to the Luoyang shovel body. A top rod for supporting reinforcing ribs is vertically welded to the upper surface of the lever, and both ends of the reinforcing ribs are welded to the upper surface of the lever. Support rods are vertically welded to the center of both sides of the lever, and the support rods are engaged with the top of the support frame assembly. The limiting component includes a first connecting rod, a second connecting rod, a first positioning rod, and a second positioning rod. The first connecting rod and the second connecting rod are arranged in parallel relative to each other. The first connecting rod and the second connecting rod are each fixedly welded with movable sleeves that are fitted onto both ends of the mounting rod near the lever. The support frame assembly includes an upright, a crossbar, a limiting frame, and a steel pad. The top of the upright is fixedly welded with a limiting frame for placing the support rod.

[0007] By adopting the above technical solution, the device uses the lever principle and the limiting frame on the support frame assembly as the fulcrum. By pressing the lever, the limiting assembly can be driven to apply an upward lifting force to the Luoyang shovel handle, eliminating the need for manual labor to pull it out or loosen it with pipe wrenches, thus greatly reducing manpower consumption.

[0008] Specifically, the first connecting rod and the second connecting rod are located on both sides of the lever, and the movable sleeve is rotatably connected to both ends of the mounting rod.

[0009] Specifically, a first positioning rod is vertically welded to the end of the first connecting rod away from the mounting rod, and one end of the first positioning rod is vertically welded to one side of the second connecting rod.

[0010] Specifically, a second positioning rod is vertically welded to the side of the second connecting rod away from the mounting rod and close to the first connecting rod. The second positioning rod is arranged parallel to the first positioning rod and a limiting cavity is provided between them for the Luoyang shovel handle to pass through.

[0011] Specifically, two uprights are arranged in parallel relative to each other, and the two uprights are located on both sides of the lever.

[0012] Specifically, the bottom ends of both uprights are fixedly connected to the upper surface of the steel pad, and a crossbar is also connected between the lower parts of the two uprights.

[0013] The beneficial effects of this utility model are as follows: The lever-type manual excavation and shovel lifting device described in this utility model utilizes the lever principle, with the limiting frame on the support frame assembly as the fulcrum. By pressing the lever, the limiting assembly can be driven to apply an upward lifting force to the Luoyang shovel handle, eliminating the need for manual labor to pull it out or loosen it with pipe wrenches, thus significantly reducing labor consumption. Especially when the Luoyang shovel is extended or the drilling depth is increased, it can effectively reduce the labor intensity of operators. Compared with the traditional manual pulling method, this device can remove the Luoyang shovel from the soil more quickly, reducing the time spent pulling out the Luoyang shovel in a single excavation operation, thereby improving the overall efficiency of the excavation operation. Because it reduces labor input and operating time, it indirectly reduces construction costs and is more suitable for large-scale geological exploration pre-exploration excavation operations. The limiting component limits the Luoyang shovel handle through the limiting cavity formed by the first and second positioning rods, which can stably drive the Luoyang shovel to move; the steel pad in the support frame component increases the contact area with the ground, and together with the connection of the crossbar, it ensures the stability of the device during use.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] As one embodiment of this utility model, such as Figures 1-3 As shown, the lever-type manual excavation and shovel lifting device of this utility model includes a lever 1, a mounting rod 2, a movable sleeve 201, a limiting component 3, and a support frame assembly 9. The mounting rod 2 is vertically connected to one end of the lever 1. The lever 1 is rotatably connected to one end of the limiting component 3 through the mounting rod 2. The limiting component 3 is sleeved on the Luoyang shovel handle 4. The bottom end of the Luoyang shovel handle 4 is fixedly connected to the Luoyang shovel body 5. A top rod 6 for supporting the reinforcing rib 7 is vertically welded to the upper end face of the lever 1. Both ends of the reinforcing rib 7 are welded to the upper end face of the lever 1. Support rods 8 are vertically welded to the center of both sides of the lever 1. The support rods 8 are snapped into the top end of the support frame assembly 9. The limiting component 3 includes a first connecting rod 301, a second connecting rod 302, a first positioning rod 303, and a second positioning rod 34. The first connecting rod 301 and the second connecting rod 302 are arranged in parallel relative to each other. The first connecting rod 301 and the second connecting rod 302 are each fixedly welded with movable sleeves 201 that are sleeved on both ends of the mounting rod 2 at the end near the lever 1. The support frame assembly 9 includes an upright 901, a crossbar 902, a limiting frame 903, and a steel pad 10. The top of the upright 901 is fixedly welded with a limiting frame 903 for placing the support rod 8.

[0018] When using the Luoyang shovel, if it is necessary to pull it out of the soil, the operator presses down on the end of the lever 1 away from the mounting rod 2. Under the action of the lever principle, the lever 1 drives the limiting component 3 to move upward through the mounting rod 2. The first positioning rod 303 and the second positioning rod 304 form an upward lifting force on the Luoyang shovel handle 4, gradually pulling the Luoyang shovel body 5 out of the soil. If the Luoyang shovel is embedded too deeply, it can be removed from the soil in stages by pressing the lever 1 multiple times.

[0019] The present invention also includes that the first connecting rod 301 and the second connecting rod 302 are located on both sides of the lever 1, and the movable sleeve 201 is rotatably connected to both ends of the mounting rod 2.

[0020] The present invention also includes a first positioning rod 303 vertically welded to the end of the first connecting rod 301 away from the mounting rod 2, and one end of the first positioning rod 303 is vertically welded to one side of the second connecting rod 302.

[0021] The present invention also includes a second positioning rod 304 vertically welded to the side of the second connecting rod 302 away from the mounting rod 2 and close to the first connecting rod 301. The second positioning rod 304 is arranged parallel to the first positioning rod 303 and a limiting cavity 11 is provided between them for the Luoyang shovel handle 4 to pass through.

[0022] This utility model also includes two uprights 901 arranged in parallel with each other, with the two uprights 901 located on both sides of the lever 1.

[0023] This utility model also includes that the bottom ends of the two uprights 901 are fixedly connected to the upper end face of the steel pad 10, and a crossbar 902 is connected between the lower parts of the two uprights 901.

[0024] In use, the limiting cavity 11 in the limiting assembly 3 is aligned with the Luoyang shovel handle 4, so that the Luoyang shovel handle 4 passes through the limiting cavity 11 between the first positioning rod 303 and the second positioning rod 304. At this time, the first connecting rod 301 and the second connecting rod 302 are sleeved on both ends of the mounting rod 2 through the movable sleeve 201 at the end, realizing the rotational connection with the lever 1. Then, the support frame assembly 9 is placed, and the two uprights 901 are placed stably on the ground next to the excavation point through the steel pad 10 at the bottom, ensuring that the uprights 901 are perpendicular to the ground. The two uprights 901 are respectively located on both sides of the lever 1. Then check whether the connection between the crossbar 902 and the two uprights 901 is firm, and ensure that the support frame assembly 9 is stable as a whole. Next, the support rods 8 on both sides of the lever 1 are inserted into the limiting frame 903 at the top of the uprights 901. At this time, the lever 1 forms a lever structure with the contact point between the support rods 8 and the limiting frame 903 as the fulcrum. When it is necessary to pull out the Luoyang shovel embedded in the soil, the operator presses down on the end of lever 1 away from the mounting rod 2; under the action of the lever principle, lever 1 drives the limiting component 3 to move upward through the mounting rod 2, and the first positioning rod 303 and the second positioning rod 304 form an upward lifting force on the Luoyang shovel handle 4, gradually pulling the Luoyang shovel body 5 out of the soil; if the Luoyang shovel is embedded too deeply, it can be removed from the soil in stages by pressing lever 1 multiple times.
